Folder Copy

Place the enclosed Net Yaroze software development disc (hereafter 'CD-ROM') in the PC CD-ROM drive and
copy the contents of each folder to the hard disk using a DOS XCOPY or Windows Program
Manager/Explorer. (At the root of CD-ROM there are two folders called PSX and GNU. You can copy these
folders anywhere on the hard disk.) In the example below, the PSX and GNU folders are copied onto the C

drive root.

Rewritingconfig.sys
Check the contents of config.sys in the root of c drive and confirm whether or not ansi.sys 1s included. If it is

not included, add the following line and reboot the system.

devicehigh=C:\WINDOWS\ansi.sys

Rewriting the Batch File

There is a file called djsetup.bat in the PSX folder which you have copied to the hard disk. Its contents are as
follows.

@echo off

set DJGPP-c:/psx/djgpp.env

PATH %path$;c:\psx\bin;c:\gnu\bin

set TMP=c:\tmp
set DTLH3000=0x3f8,4,9600

If the psx and gnu folders are not on c drive root, amend this file so the contents correspond to the location and

names (if you have changed these) of the copied folders. This procedure is described below.

Note

C

Because the file is copiedrom the CD-ROM, thefile is read only. Before editingchange this in DOS as blow.

:\PSX> attrib -r djsetup.bat (where'c:\PSX is the path

The second line is the set up of the environment variable DJGPP. The compiler's environment setting
file is specified. If appropriate, modify the c:/psx part so it refers to the correct path and name of the
copied folder. Note that you must use a / (forward slash) to delimit the path for this environment

variable only.

The third line is the setting of the environment variable PATH. Rewrite thec:\psx and c:\gnu part to

the name and path of the copied folder if appropriate.

The fourth line is the working folder. Create and allocate a folder if c:tmp is not appropriate.

For example, change the line to:

set tmp=c:\yaroze\wrk (where'wrk' is your preferred working folder)

The fifth line is the setting relating to communication with the NetYaroze PlayStation. Specify the
port address, IRQ and speed (in this order) separated by the defaults, OX3F8 and IRQ4, are the
general address and IRQ of COMI.

Specify 0X2F8 as the address and IRQ3 if you use COM2.

Communication speeds ofup to 115200bps are supported. Specify either 9600, 19200, 38400, 57600

or 115200 according to the processing capacity of your PC.

(Please note that if you wish to use speeds other than 9600 baud, you should place a standard
formatted PlayStation Memory card in your Net Yaroze PlayStations Memory card Slot 2 and change
the rate using SIOCONS- See chapter 170f the Net Yaroze User Guidefor details of SIOCONS)

Execution of the Environment Setting Batch F ile

From the PSX folder (or your chosen folder name) in DOS (or the DOS box from Windows) execute the

rewritten batch file djsetup.bat, as below.

C:\PSX>djsetup (where'PSX is your chosen folder name)

This completes thepreparation of the development environment

Getting Started

There are some sample and quick start programs which you can use to test you NetYaroze system set up and

get started on compiling and running some programs.

Programmers with a lot of experience, may wish to go straight to theSample Program section of this chapter,
which skips a lot of explanation. The Quick Start section covers the same process, but gives a little more

detail as it steps through NetYaroze software development.

Quick Start

The 'quick' directory on the Net Yaroze PC CD holds some quick start test programs. You probably copied it

to your PC's hard disk together with all the NeYaroze software.

Using the quick start programs you can quickly check that everything is working on your NYtaroze system.

Net Yaroze Program Development - Overview

Here are the basic steps that you need to take to develop software on the NetYaroze system. (See the Net

Yaroze User Guide chapter 13for more details on the development cycle.)

l. Create/edit text files which contain the C code.
Also known as the 'source code', these are usually namedihme.c' (where 'name' is the selected file
name).

(There are two source code files already in the quick directory: tuto0.c and tutol.c.)

2. Compile and link the C files to crate the executable file (the file that is the finished
program/application).

(In the test example, below, we use amakefile, called by the command 'make' to do this.)

3. Use the SIOCONS console tool, provided as part of your Nét aroze software, to establish contact

between your Net Yaroze PlayStation and PC.

4. Run the executable program.

5. (In this test example, there are two batch files - batchO and batchl - which you can use to run the

executable files (or 'executables') of the test programs.)

Compile and Run the Quick Start Programs - Step by Step
l. Set up your NetYaroze PlayStation as described in theStart Up Guide link the Net Yaroze

PlayStation to your TV and PC, and insert a Controller in thPlayStation's Controller port 1.

2. Turn on the PC, TV and NetYaroze PlayStation and wait for the ready-to-go screen to appear on the

TV, as shown below.

DTL-53035-CONSOLE
FE) TEE | ЕЛЕЕ ЕЛЕЕ ЕЛШЕ

This screen should appear within 30 seconds of turning on or resetting the NeYaroze PlayStation, after the

Sony and PlayStation logo screens.

On the PC, bring up an MS-DOS box and, from the PSX folder (or your chosen Náfaroze folder

name), invoke the NetYaroze environment setting batch file as follows:

c:\PSX>djsetup (where 'PSX' 15 your chosen NefYaroze folder name)

Compile the quick start programs. Use the 'make' utility to do this by typing 'make' to the DOS

prompt to create the executable programs from the source files.

c:\psx\quick>make

Bring up the console tool, SIOCONS.(You must have set up the quick directory as a path for
SIOCONS in yourautoexec.bat file.)

c:\psx\quick>siocons

or, if you have already changed the baud rate, type

C:\psx\quick>sicons -B<baud rate» (where '<baud rate>' is the value of your chosen
rate)

Now you are in SIOCONS, the console tool used to communicate with the N&taroze PlayStation

from the PC.

The PC monitor output should look similar to this:

c:NpsxNquick»siocons -B115200

siocons -- PlayStation debug system console prog
for DTLH3000 1996/05/10 00:00:03

when hung up try type ESC
I/O addr = 0x03F8, IRO=4 (vect=0x000C,8259=20)
BAUDRATE = 115200

Check that SIOCONS is working correctly by pressing return: if all is well, the SIOCONS prompt

will appear, which is a double-right arrow: >>

6. Run the quick start batch files.

First, press [F3] on the PC keyboard. This brings up th@uto[1]: prompt. Then enter the name of
the batch file;batcho.

For example (after pressing, [F3] on the PC keyboard):
Auto[1]:batchO
Batch0 downloads and runs tuto0.exe.

J: Immediately after starting the dowioad, downloading messages appear on the PC monitor, similar

to the following.

tutoO [ .text] address:80100000-801001ef size:0001f0 0001f0: lsec.

tutoO [.rdata] address:801001f0-8010020f size:000020 000020: lsec.

tutoO [ .data] address:80100210-8010035f size:000150 000150: 2sec.

tutoO [.sdata] address:80100360-801003df size:000080 000080: 2sec.
8. The TV screen shows downloading messages, similar to those below:

BINARY DATA TRANSFER - BWR

ADRS = 80100000

SIZE = 000001F0 BYTES

INTO BURST TRANSFER SUM:111F0/1FO BYTES
DONE.

Running and Terminating a Program
TutoO (called by batch0) prints 'Hello World!' to the SIOCONS console on the PC, and terminates

automatically.

When you have run and terminated a program, the Net Yaroze PlayStation resets itself, going back to the
ready-to-download screen (as shown in [2] ofCompile and Run the Test Programs - Step by Step, above, and

SIOCONS displays its prompt again (>>).

Once the PlayStation and PC are reset, you can run the second quick start program, tutol, by following the

steps described in [8] and [9] ofCompile and Run the Test Programs - Step by Stepbove.

Tutol (called by batch1) prints 'Hello World!' to the TV screen. Terminate this program by pressing SELECT

on the Controller.

Exiting SIOCONS
To quit SIOCONS and return to the MS-DOS prompt, on the PC keyboard, press [F10] and then [F2]or just
press [Esc].

Using the Test Files
The source files, makefile and batch files are all simple text files which you can easily edit (Using the text

editor in DOS, for example) to see their contents.

To edit or look at the tuto0.c source code, using the text editor in DOS, type:

e:\>psx\quick>textedit tuto0.c

Look at the test and other sample code to familiarise yourself with what the NetYaroze system can do, and

how to achieve this by writing C programs.

Quick Directory Contents

Sample Program

In order to check your environment, try downloading the sample program provided. (The source code and

executable file are in thepsx sample check folder- where 'psx' is your chosen file name)
